This posts data, similar to the other --data options with the exception
that this performs URL-encoding.

To be CGI-compliant, the <data> part should begin with a *name* followed
by a separator and a content specification. The <data> part can be passed to
curl using one of the following syntaxes:

## content
This makes curl URL-encode the content and pass that on. Just be careful
so that the content does not contain any = or @ symbols, as that makes
the syntax match one of the other cases below!

## =content
This makes curl URL-encode the content and pass that on. The preceding =
symbol is not included in the data.

## name=content
This makes curl URL-encode the content part and pass that on. Note that
the name part is expected to be URL-encoded already.

## @filename
This makes curl load data from the given file (including any newlines),
URL-encode that data and pass it on in the POST.

## name@filename
This makes curl load data from the given file (including any newlines),
URL-encode that data and pass it on in the POST. The name part gets an equal
sign appended, resulting in *name=urlencoded-file-content*. Note that the
name is expected to be URL-encoded already.
